1-2 Points, Lines, Rays, Segments & Planes
[size=150][size=200][color=#0000ff]What are points, Lines, Rays, Segments & Planes and how do we name them?[/color][/size][/size]
#1
[size=150]a. Give two other names for line ST and plane R.[br][br]b. Name 3 points that are collinear.[br][br]c. Name 3 points that are coplanar[/size][br][br][color=#ff0000][b][size=150]Example format for answering:[br][br]a. Line QP[/size][/b][/color]
[color=#38761d][b][size=150]d. Give another name for segment GH. How can you tell if I am referring to line GH or segment GH and how are they different?[br][br]e. Name all rays with endpoint J. How can you tell a ray from a line, or a segment? Which rays are opposite rays?[/size][/b][/color]
Find where lines and planes intersect and name them!

#4 Directions for Geogebra Activity Below ( you can always undo and redo by using the arrows in Geogebra)
[b]a. Create a point named after the letter first letter of your last name[/b][br][b]b. Create line AB[/b][br][b]c. Create line CD that intersects line AB at point Z[/b][br][b]d. Create a ray using the initials of your first and last name in order[/b][br][b]e. Create a segment with those same initials and measure it[/b][br][b]f. Create ray HI[/b][br][b]g. Create ray IH[/b][br][b]h. Create a segment 10 units long[/b]
